This feels to me like a new feature for arm64, one that has never worked before and you are just making it feature-parity with x86, right? Or is this a regression fix somewhere? Why is this needed in 5.15.y and why can't people who need this new feature just use a newer kernel version (5.19?) thanks, greg k-h
